The edge of the narrative frame we're in starts to split the right side of the page from the left side. On the right side of the page, Harry arrives in front of Dumbledore's door. On the left side of the page, Draco and Luna arrive in front of a grey door. In between, there's a sliver of a view of present Harry in the interrogation cell.
